What are the main defects that the Wellman X-ray inspection system can find on the electrolytic capacitor?

There are two main types of capacitors used on printed circuit boards (PCB), Multi-layer Ceramic Capacitors (MLCC) and electrolytic capacitors. Today we mainly talk about electrolytic capacitors. The capacitance per unit volume of electrolytic capacitors is very large, tens to hundreds of times larger than other types of capacitors; the rated capacity can be very large, and can easily be tens of thousands of μf or even a few f; [...]

What are the main defects that the Wellman X-ray inspection system can find on the LED light?

LED light SMD LED lights are the most important and common components in LED related products such as LED strips and LED boards. The welding quality of SMD LED light directly affects the quality and life of lighting products.Similar to the PCB BGA, the SMD LED lights are also soldered to the LED strips and LED boards, similarly, there will also be welding problems such as solder voids. [...]

What are the main defects that the Wellman X-ray inspection system can find on the through-hole PTH of PCB?

PTH (Plating Through-hole) is a common process on a printed circuit board (PCB), but the surface of the hole drilled directly on the PCB is only resin, which is not conductive. Therefore, we plated a layer of copper on the surface of the drill hole, so that different copper foil layers can conduct electricity. through-hole PTH When we insert the pins of the components [...]

What are the main defects that the Wellman X-ray inspection system can find on the QFP & QFN of PCB

Flat no-leads packages such as quad-flat no-leads (QFN) and dual-flat no-leads (DFN) physically and electrically connect integrated circuits to printed circuit boards. Flat no-leads, also known as micro leadframe (MLF) and SON (small-outline no leads), is a surface-mount technology, one of several package technologies that connect ICs to the surfaces of PCBs without through-holes. A QFP or Quad Flat Package is a surface-mounted integrated circuit package with "gull [...]

What are the main defects that the Wellman X-ray inspection system can find on the BGA of PCB?

The X-ray inspection system is most used to test the quality of a printed circuit board (PCB) soldering. BGA is the most important component of a PCB. Its soldering quality directly affects the quality and function of the PCB. So, what are the BGA soldering defects? How can it be identified as a defect? During the BGA soldering process, affected by factors such as the amount of printed [...]
